LLS2W151MELB

The LLS2W151MELB is an aluminum electrolytic capacitor from Nichicon's LLS series featuring a snap-in terminal design and a 150 μF capacitance at a 450 V rating. It is designed for general-purpose applications that require a high-voltage, high-ripple-capacity electrolytic solution in a radial, snap-in can.

Key value propositions include rated 450 V operation, high ripple current capability at both low and high frequencies, long endurance under load (3000 hours at 85°C), and RoHS compliance—providing a specification-driven choice for engineers and procurement teams.

Key Features

• Capacitance and Voltage 150 μF nominal capacitance with a ±20% tolerance and a rated voltage of 450 V, suitable for high-voltage general-purpose use.
• Snap-in Terminal Package Radial, can-type snap-in mounting for secure board-level installation and reliable mechanical retention.
• Ripple Current Performance Rated ripple currents of 1.29 A at 120 Hz and 1.845 A at 50 kHz, supporting both low- and high-frequency ripple demands.
• Leakage Current Specified leakage current of 770 μA, measured per the product specification conditions.
• Endurance and Temperature Endurance of 3000 hours at 85°C with DC bias plus rated ripple current applied; operating temperature range of −25°C to +85°C for the 350–450 V range.
• Physical Size and Packaging φ30×25L dimensional profile (L: 2.5 × D: 3.0 cm) and tray packing; mass production status for consistent availability.
• Regulatory Compliance RoHS compliant in accordance with the LLS series specification.

Typical Applications

• General Purpose For general-purpose circuits that require a 150 μF capacitor rated to 450 V with snap-in mounting.
• General Purpose Suited to designs needing sustained ripple handling at both 120 Hz and 50 kHz frequencies with defined ripple current ratings.
• General Purpose Appropriate where long endurance at elevated temperature is required—3000 hours at 85°C under rated conditions.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage general-purpose circuits without changing capacitor family.
• Dual-frequency ripple handling: Specified ripple current at 120 Hz (1.29 A) and at 50 kHz (1.845 A) supports both low- and high-frequency ripple requirements.
• Long endurance under load: Rated for 3000 hours at 85°C with DC bias plus rated ripple current, providing predictable aging characteristics.
• Compact snap-in form factor: φ30×25L radial can with snap-in terminals for secure board mounting and straightforward assembly.
• RoHS compliant: Meets RoHS directive requirements as declared for the LLS series.
• Production readiness: Tray packing and mass production status support design-in and volume procurement.
